Abstract

The invention discloses an obtaining device and obtaining method for the position of a central axis of a main shaft of a machine tool. The obtaining device comprises a Hexapod mobile platform, an auxiliary calibrating piece, a laser sensor and a controller, wherein the Hexapod mobile platform comprises an upper platform, a lower platform and six telescopic rods; the lower platform is mounted on a cutter frame; a cutter is mounted at the central position of the upper platform; the Hexapod mobile platform has six freedom degrees; the auxiliary calibrating piece is mounted at the end part of the main shaft of the machine tool, and comprises a flat cylindrical end plate perpendicular to the main shaft of the machine tool; the laser sensor is mounted on the upper platform; the controller can control the upper platform of the Hexapod mobile platform to move along one or more freedom degrees of the six freedom degrees, and control the laser sensor to scan the flat cylindrical end plate in the moving process of the upper platform; and the controller obtains a straight line equation of the position of the central axis of the main shaft of the machine tool in a Hexapod coordinate system according to scanning data. According to the obtaining device and the obtaining method disclosed by the invention, the position equation of the central axis of the main shaft of the machine tool can be quickly and accurately obtained without performing sacrificial cutting on a work piece, so that the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a device and method for acquiring the central axis position of a machine tool spindle. Background technique [0002] Before operating a lathe for cutting, it is usually necessary to determine the position of the central axis of the lathe spindle, that is, the position of the workpiece rotation axis. At present, many methods of manually obtaining the central axis of the lathe spindle are known. For example, there are patent documents that describe the estimation of the central axis of the lathe spindle by tentative cutting and using a touch measuring probe to measure the position of the radially opposite point of the workpiece. Methods. However, using this method takes a long time, seriously affects the processing efficiency, and requires sacrificial cutting of the workpiece to be processed, which is difficult to meet the requirements of modern industrial manufacturing. [0003] The above information disclosed in this Backgrou...
